The bottom of the outer side wall of the connector 1 is fixed with a plurality of second rotating seats 4 corresponding to the first rotating seats 3.

The clamping jaw 2 comprises a first base 5, a second base 6, an intermediate lever 7 and a jaw sleeve 8.

The top end of the first base 5 is hinged with the second rotating seat 4. A third rotating seat 9 is fixed on the outer side wall of the first base 5, and an oil cylinder 10 is hinged between the first rotating seat 3 and the third rotating seat 9.

The second base 6 is fixedly connected to the bottom end of the first base 5. The middle rod 7 is fixedly connected to the bottom center of the second base 6. The middle rod 7 is internally provided with a cavity 11, and the cavity 11 extends to the inside of the second base 6. The outer side walls of the left side and the right side of the middle rod 7 are respectively provided with a plurality of second connecting holes 12 communicated with the cavity 11. Slide holes 13 communicated with the cavity 11 are formed in the outer side walls of the left side and the right side of the second base 6. The outer side walls of the left side and the right side of the second base 6 are also provided with protective sleeves 14. The protective sleeve 14 comprises a stationary ring 15 and a swivel cap 16. The fixing ring 15 is fixedly connected with the first base 5 and is arranged around the sliding hole 13. The outer side wall of the fixing ring 15 is provided with an external thread. The rotary cap 16 is sleeved outside the fixed ring 15, and an inner thread which is in fit connection with the outer thread is arranged on the inner side wall of the rotary cap. Two sliding plates 17 are slidably connected in the cavity 11. A plurality of connecting rods 18 are fixed on the sides of the two sliding plates 17, which are away from each other. The other end of the connecting rod 18 passes through the cavity 11 through the second connecting hole 12.

A driving structure for driving the two sliding plates 17 to move simultaneously is provided in the cavity 11. The drive structure comprises a first spring 19 and two pressing bars 20. The first spring 19 is fixedly connected between the two sliding plates 17. The two pressing rods 20 correspond to the two sliding holes 13 respectively. One end of the pressing rod 20 penetrates into the cavity 11 through the sliding hole 13 in a sliding connection manner and is fixedly connected with the sliding plate 17. The other end of the pressing lever 20 is located outside the second base 6 and is fixed with a pressing plate 21 located inside the protective sheath 14.

The claw sleeve 8 is sleeved outside the middle rod 7, and a plurality of first connecting holes 22 which correspond to the second connecting holes 12 and can be used for inserting the connecting rod 18 are formed in the inner side walls of the left side and the right side of the claw sleeve 8.

Working principle: the claw sleeve 8 is sleeved outside the intermediate rod 7, only the claw sleeve 8 is in contact with the goods in the working process, and the intermediate rod 7 is not in contact with the goods. Thus, the intermediate lever 7 is not damaged, and only the claw sleeve 8 is damaged during use. Only the claw sleeve 8 needs to be replaced, so that the replacement cost is reduced.

When it is desired to disassemble the claw sleeve 8, the rotary cap 16 is rotated to remove the rotary cap 16 from the stationary ring 15.

The claw sleeve 8 is sleeved outside the middle rod 7, so that the damage of the middle rod 7 in the using process is avoided, after the clamping jaw 2 is damaged, only the claw sleeve 8 needs to be replaced, the replacement cost is reduced, the replacement process is simple and convenient, and the time and the labor are saved.

Embodiment two:

the difference from the first embodiment is that the outer side wall of the second base 6 is not provided with the protective sleeve 14, and the driving structure does not include the first spring 19 and the pressing rod 20, but includes the positive and negative screw rod 23, the driven rotating rod 24 and the driving rotating rod 25 as shown in fig. 5 to 7. The top end of the driven rotating rod 24 is rotatably connected with the inner top wall of the cavity 11 through a bearing. The driven gear 26 is fixedly sleeved outside the driven rotating rod 24. The top end of the positive and negative tooth screw rod 23 is fixedly connected with the bottom end of the driven rotating rod 24. The bottom end of the positive and negative tooth screw rod 23 is rotationally connected with the inner bottom wall of the cavity 11 through a bearing. The positive tooth part and the negative tooth part of the positive tooth screw rod 23 are both sleeved with a nut seat 27 in a sliding way, and the nut seat is connected with the positive tooth part and the negative tooth part in a threaded way. Both the front and rear ends of the nut seat 27 are attached to the inner side walls of the cavity 11. The left and right ends of the nut seat 27 are hinged with a linkage rod 28. The other end of the link lever 28 is hinged to the slide plate 17. One end of the driving rotary rod 25 is rotatably connected with the cavity wall of the cavity 11 through a bearing. The driving gear 29 meshed with the driven gear 26 is fixedly sleeved outside the driving rotating rod 25. The other end of the driving rotating rod 25 penetrates out of the second base 6 and is provided with a sliding groove 30. The outer side wall of the driving rotating rod 25 is provided with two through holes 31 communicated with the sliding groove 30. One through hole 31 is close to the second base 6, and the other through hole 31 is far from the second base 6. A slide bar 32 is slidably connected to the slide groove 30. The outer side wall of the slide bar 32 is provided with a groove 33 corresponding to the through hole 31. A connecting block 34 is slidably connected in the groove 33. A second spring 35 is fixedly connected between one end of the connecting block 34 and the bottom of the groove 33. The other end of the connection block 34 passes out of the groove 33 and through the through hole 31 and is provided in an arc shape. One end of the slide bar 32 passes out of the slide slot 30 and is fixed with a knob 36. A pull ring 37 is fixed to the end of the knob 36 facing away from the slide bar 32. A clamping rod 38 is fixed on the outer edge of the knob 36. A snap ring 39 is fixed on the outer side wall of the second base 6 and is sleeved outside the knob 36 and the driving rotating rod 25. The end of the snap ring 39 facing away from the first base 5 is provided with a notch 40 into which the clamping rod 38 can be inserted.

Working principle: when the claw sleeve 8 needs to be disassembled, the knob 36 is pulled through the pull ring 37. The knob 36 pulls the slide bar 32. Since the end of the connection block 34 passing through the through-hole 31 is provided in an arc shape, the end is in contact with the wall of the through-hole 31 near the second base 6, and the force acting on the end can be decomposed into a force directed into the groove 33. Thus, the connection block 34 is pressed back into the groove 33, and the second spring 35 is compressed to form a repulsive force. The slide bar 32 is gradually pulled out of the slide slot 30. When the groove 33 corresponds to the through hole 31 of the second base 6 according to another principle, the connection block 34 passes through the through hole 31 under the action of the elastic force of the second spring 35, thereby fixing the slide bar 32. At this time, the clamp rod 38 is completely withdrawn from the notch 40. The slide bar 32 is then rotated by rotating the knob 36 clockwise, and the slide bar 32 rotates the drive lever 25. The driving rotary rod 25 drives a driving gear 29 fixedly connected with the driving rotary rod to rotate. The driving gear 29 rotates the driven gear 26 engaged therewith. The driven gear 26 rotates the driven rotating lever 24 fixedly connected thereto. The driven rotating rod 24 drives the positive and negative tooth screw rod 23 fixedly connected with the driven rotating rod to rotate. The positive and negative tooth screw 23 drives the two nut seats 27 to move oppositely. The nut seat 27 pulls the two sliding plates 17 to move toward each other through the link lever 28. The sliding plate 17 drives the connecting rod 18 to be withdrawn from the first connecting hole 22 until the connecting rod 18 is completely located in the second connecting rod 18 and the cavity 11. At this time, the claw sleeve 8 can be removed from the outside of the intermediate lever 7.

Similarly, when the claw sleeve 8 needs to be installed, the claw sleeve 8 is sleeved outside the middle rod 7. The positions of the first and second connection holes 22 and 12 correspond. The knob 36 is then rotated counterclockwise. The front and back tooth screw rods 23 drive the two nut seats 27 to move oppositely, and the two nut seats 27 drive the two sliding plates 17 to move reversely. The sliding plate 17 can drive the connecting rod 18 to pass through the cavity 11 through the second connecting hole 12 and be inserted into the first connecting hole 22, thereby completing the fixed installation between the middle rod 7 and the claw sleeve 8. The slide bar 32 is then pressed into the slide slot 30. Until the groove 33 corresponds to the through hole 31 near the second base 6, the connection block 34 passes through the through hole 31, thereby fixing the slide bar 32. At this time, the clamping rod 38 is completely inserted into the notch 40, so that the knob 36 cannot be rotated, and unnecessary rotation of the knob 36 is avoided.
